Thanks for the thumbs up. I'm not going to say there is only one way that suits everybody but I do make recommendations based on what I've experienced firsthand. That said, if I owned the Simonson Thor omnibus or any of the other extra thick tomes from the early omni era, I would probably store that one volume flat to prevent the text blocck sag frequently mentioned on here. I would just store it solo, which I'm sure goes against the OCD tendencies of many shelf porn enthusiasts.
